Abstract
Glass transition temperatures and the corresponding activation energie s of poly(carbonates) and poly(thiocarbonates) with different side-cha in substituents obtained from diphenols with methyl groups in the 3-po sition in the phenyl rings have been determined by differential scanni ng calorimetry at several scanning speeds. Partial specific volume and specific refractive index increments have also been obtained by densi metry and refractometry measurements in benzene at 25 degrees C. The e ffect of the different substituents on these properties has been analy sed. (C) 1998 SCI.
